Embodiment

Many mobile wireless devices include Long Term Evolution (LTE), WLAN (WLAN) and/or bluetooth (BT) transmitting-receiving Device.Space and cost constraint due to wireless device, LTE, WLAN and BT transceiver share one or more antenna.This day It is possible that line is shared, because LTE, WLAN and BT agreement are operated all in 2.3-2.5GHz frequency bands.Due to LTE signals, Frequency between WLAN signal and BT signals is approached, in certain operations scene, and mobile wireless device is adjacent or close to phase It is transmitted and receives simultaneously in adjacent frequency band.This makes LTE, WLAN and BT receiver easily be influenceed by sensitivity decrease.

It is described herein with switched using antenna with realize in same wireless equipment use different communication protocol multiple receipts Send out the example of the system, method and other embodiments that association coexists of device.Although will be in LTE communication agreement, WLAN communication protocols Antenna switches described in background with BT communication protocols, but can solve any number of different communication with antenna switching Sensitivity decrease caused by agreement.

Switched using antenna, one or more shared antenna on switching wireless device, so that antenna is based on transceiver Operating condition be connected to selected transceiver.Antenna is connected to transceiver when transceiver is in transmission or reception action. In this way, transceiver does not handle the unexpected signal for transceiver to reduce the signal in adjacent frequency band to transmitting-receiving The influence of device sensitivity decrease.

Many modern handsets are via LTE protocol, WLAN protocol and/or BT protocol communications.In time division multiplexing (TDM) mould LTE communication in formula come across scope from 2300MHz to 2400MHz " in frequency band 40 ".In FDD (FDD) pattern LTE communication come across scope from 2500MHz to 2570MHz " in frequency band 7 ".WLAN and BT scope from 2400MHz to It is transmitted and receives in 2483.5MHz 2.4GHz industry, science and medical treatment (ISM) frequency band.Therefore, LTE communication comes across It is adjacent or close in adjacent frequency band with there is the ISM band of WLAN/BT communications.
